Roton-pair creation by electron bubbles in helium

Physical Review B, 1995
Electrons in superfluid helium form cavities that displace hundreds of atoms. These ``electron bubbles'' characteristically emit rotons in pairs when accelerated by an electric field. As no symmetry prevents the emission of single rotons, this has long been a mystery.

2D Electron Bubbles in Gaseous Helium

Journal of Low Temperature Physics, 2005
The structure of 2D electron bubbles in gaseous helium is discussed. These cavities appear under the condition ng > nc, where nc ≈ 1020 cm−3 is much less than the critical helium gas density for the appearance of 3D electron bubbles. Far from the critical density, the 2D bubble trapping energy is practically a linear function of ng. Experiment confirms
